What are metrics and visualizations in Grafana?
In Grafana, metrics are data points collected over time, often represented as time-series data. Visualizations are graphical representations of metrics, such as charts, graphs, and gauges.
With Grafana's vast array of visualization options, you can create line graphs, bar charts, heatmaps, tables, and more, allowing you to gain insights into your data quickly and efficiently.
What is the difference between Grafana vs Prometheus?
While Grafana and Prometheus are often used together, they serve different purposes:
Grafana is primarily used for data visualization and monitoring dashboard creation. It provides a flexible and interactive interface for visualizing metrics from various data sources.
Prometheus, on the other hand, is a time-series database and monitoring system. It collects and stores metrics and offers alerting capabilities. Grafana can be used as a frontend to query and visualize data stored in Prometheus.
